WARNING:
RISK OF ELECTRICAL SHOCK —EQUIPMENT MUST BE PROPERLY GROUNDED. Your Harris equipment requires a properly grounded three-prong power receptacle for safe operation. Have the receptacle checked by a qualified electrician be-fore connecting this equipment. Do not cut or remove the third (ground) prong from the power transformer.
Do not use two-prong extension cords or adapters to defeat the safety features of this equipment. If you have a two-prong receptacle, it must be replaced with a three-prong receptacle, installed by a qualified elec-trician.
not allow anything to rest on the power cord. Do not locate this product where the cord will be abused by persons walking on it.
Do not overload wall outlets and extension cords as this can result in the risk of fire or electric shock.
Never push objects of any kind into this product through cabinet slots as they may touch dangerous voltage points or short out parts that could result in a risk of fire or electric shock. Never spill liquid of any kind on the product.
To reduce the risk of electric shock, do not disassemble this product, but take it to a qualified serviceman when service or repair work is required. Opening or removing covers may expose you to dangerous voltages or other risks. Incorrect reassembly can cause electric shock when the appliance is subsequently used.
Unplug this product from the wall outlet and refer servicing to qualified service personnel under the following conditions:
A. When the power supply cord or plug is damaged or frayed.
14.
15. C.
D.
E.
F .
If the product has been exposed to rain or water.
If the product does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions.
Improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the product to normal operation.
If the product has been dropped or the cabinet has been damaged.
If the product exhibits a distinct change in performance.
Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk electric shock from lightning.
Do not use the telephone to report a gas leak in the vicinity of the leak.
SAVE THESE INSTRUCTIONS.
General Information
of
Please adhere to the following precautions:
1.
2.
3.
4.
Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
Recorder Logging
A tape recording may be desirable for evidence to prove that certain announcements or warnings were made over the paging system. The normally open contacts
(terminals 16 & 17, see Figure 2-1) may be used to activate a tape recorder to record all tones and
announcements that were made, without the background music in between which would consume large amounts of tape.
Balanced to Unbalanced
The balanced inputs of the AT&T PagePal may be
driven by an unbalanced source. Simply connect the two wires to the + and – input terminals.
Unbalanced inputs to power amplifiers may be driven from the PagePal’s balanced output by connecting the PagePal ground (terminal 14, see Figure 2-1) to the input ground of the power amp, and the + or – output (terminal 13 and 15, see Figure 2-1) of PagePal to the “hot” input pin of the power amp. However, the output level will be 6dB less.

Level Controls
Main Output
Adjusts level of output. Full counter-clockwise rotation provides unity gain from Telephone input to PagePal output. This is best for driving AT&T PagePals, or consumer (home Hi-Fi) type amplifiers.
Full clockwise rotation provides 14dB gain.* This will be more appropriate commercial-industrial sound equipment. Refer to the specifications of your power amplifier for the appropriate input level, or experiment with the adjustments for best results.
Set the Main Output level first using telephone input, then adjust Attendant and Music inputs for an appropriate relative level. (Telephone input signals are typically -15 to -10dBm.)
Attendant Input
Adjusts level of Attendant Input relative to the Telephone Input. Adjustment range is from 0dB to less than -30dB.
Music Input
Adjusts the level of Music Input relative to Telephone Input. Adjustment range is from 0dB to less than -30dB.

Important Information
This equipment is for use on telephone wiring containing a secondary circuit protector. This paging equipment requires
a Harris Dracon model 22060-930 PageGuard Secondary Circuit Protector where applicable (see Figure C-1).
Each PagePac unit is supplied with a PageGuard protector factory-installed on the principal Tip-Ring pair. Each terminal pair on Terminal Strip “B” (see Figure C-2 of the PagePac manual) that is to be connected to any wires that go off premises must be supplied with an additional PageGuard protector.
The secondary circuit protector must be located between the primary protector and the paging equipment. Refer to the Safety Information and Installation Steps below.
Safety Information
■
■ ■
■
■
The PageGuard is used when connecting paging equipment directly to telephone lines that maybe exposed to high voltage power lines.
Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
